Grade IX: Topographical Features of the Northern Mountains
This lesson will cover the topographocal or relief features associated with the Northern Mountains of Pakistan
2
Quick Facts about the Topography of the Northern Mountains
Parallel ranges run mainly from West to East
The height of the ranges increases from South to North
Attain high altitude - rise to over 6000 m up to 8475 m
3

Pass
Snow fields / glaciers
Attain high altitude - rise to over 6000 m up to 8475 m
Snow-capped peaks/steep slopes

How are V- Shaped Valleys Formed?
A V-shaped valley is a narrow valley with steeply sloped sides that appear similar to the letter "V" from a cross-section. They are formed by strong streams, which over time have cut down into the rock through a process called downcutting. These valleys form in mountainous and/or highland areas with streams or rivers in their "youthful" stage. At this stage, streams flow rapidly down steep slopes.
5
How are U- Shaped Valleys Formed?
A U - shaped valley is formed by erosion from glaciers

Multiple Select
(Choose the three correct options) V Shaped valleys
7
What are glaciers?
A glacier is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries.
8
What are glacier landforms?
Glacial landforms are landforms created by the action of glaciers. Most of today's glacial landforms were created by the movement of large ice sheets during the Quaternary glaciations
9
A cross sectional look at alpine glacier landforms
Glacial landforms are landforms created by the action of glaciers. Most of today's glacial landforms were created by the movement of large ice sheets during the Quaternary glaciations. Continental glaciers on the other hand are found in Antarctica and Greenland.
10
What is a horn?
A horn results when glaciers erode three or more arêtes, usually forming a sharp-edged peak. Can you identify the horn in this picture?
11
What are arêtes?
An arête is a narrow ridge of rock which separates two valleys. It is typically formed when two glaciers erode parallel U-shaped valleys. Arêtes can also form when two glacial cirques erode headwards towards one another, although frequently this results in a saddle-shaped pass, called a col.
12
What is a cirque?
A cirque is a half-open steep-sided hollow at the head of a valley or on a mountainside, formed by glacial erosion.
13
What is a tarn?
Tarn, a small mountain lake, especially one set in a glaciated steep-walled amphitheater known as a cirque.

15
What is a Scree?
Scree is a collection of broken rock fragments at the base of crags, mountain cliffs, volcanoes or valley shoulders that has accumulated through periodic rockfall from adjacent cliff faces.
16
What is a valley step?
A valley step is a prominent change in the longitudinal slope of a valley, mainly in trough valleys formed by glaciers. Typically, a valley formed by glaciers has a series of basins with intervening steps formed by the locally varying erosion depths of valley glaciers.
